Tables :: Calling Subroutine From VBA Routine To Append Record

Public Sub UpdateLotsizes()
Dim curDatabase As DAO.Database
Dim ProdPlanDB As DAO.Database
Dim rstQryLot As DAO.Recordset
Dim rstInvLoc As DAO.Recordset

ExceptionReportAddRecord

Public Sub ExceptionReportAddRecord()
Dim rstExcRpt As Recordset

With rstExcRpt
.AddNew
.Fields("item_no").Value = txtItemNumber

[Code] .....
